Collins International Lower Secondary Computing series provides in-depth coverage of the Cambridge curriculum frameworks Lower Secondary Computing (0860) and Lower Secondary Digital Literacy (0082), as well as the UK national curriculum for Computing at secondary level. The Teacher's Guide offers a detailed lesson plan for every unit, giving guidance on how to run the session, including lesson objectives, reference to key pedagogies, mapping grids, worksheets, resource sheets, answers, support for assessing end-of-chapter projects and ' Build on this' extension activities. The lesson plans and introduction provide valuable subject knowledge and support for non-specialists. This includes summaries of the key computing pedagogies used in the resources, and references to further reading. The accompanying downloads, available on the Collins site, includes PDF and editable Word versions of all the resources in the Teacher's Guide, to print and adapt, as well as source files, mapping grids, worksheets, resource sheets and recommended sites to support practical tasks with a host of resources to supplement teaching.
